AUTOMATIC SA'IFE'S nnvIc Yb-aZZcrhmni/f concern: 7 Be it known that l, HERMANN 'JENsEN, of Copenhagen, Denmark, No-4 Svanemosegaardsvej, have invented new and useful Improvements in Automatic Sales Devices, .of which the following is a true and exact description.

My invention concerns anarrangement of automatic sales devices, andthe object .of the invention is partly to insure the reliable closing of the space for the goods, against the use of worn coins, or those which are too small, and partly to permit the opening of :the door in the simplest possible manner,

when a proper coin is thrown in.

The invention is shown in the drawing,

Against the rim of lockwing 3 is pressed a stopper 7, by means of a spring 6, the former revolving around a pin 8. The stopper 7 has a strengthening member 9, through which a small pointed screw 10 is carried. The chute 11 for the coins is slightly inclined, and only permits one coin of the desired kind to pass at a time. The coin chute 11 terminates in a closed part 12, which emerges above the funnel l3. This latter has on the right side a notch 14, through which the point of screw 10 enters the funnel.

When no coin is inserted, the stopper 7011' the handle of the door being pulled will enter the notch 4 and thus lock the door. When a proper coin is inserted it will, as shown in Fig. 1, prevent a forward movement of screw 10, by jamming itself firmly between screw 10 and the opposite wall of funnel 13. The stopper 7 can thus not move farther. forward and by a turning of the door notch 4 will pass by the point of stopper 7 without the stopper 7 interfering with the movement of the door.

When the heel 5 of the lockwing 3 passes Specification of Letters Patent.

the point .of stopper 7 it will. force this latter a little back, which will remove screw 10 from the coin, which latter will fall-down through chute $15 to drawer 16. In order to separate. worn coins, apiece .of the bottom of the com chute-11 18 cut away, andkthe flllSslng lJaTt 1S replaced by a 10089131643917 7 fastened bysome elastic wire 18, which turns on a pin 19 fastened :to chute-'11, From the pin '19 extends an arm 20 in :the end of which is. a screw 21, of, which-wthe, point, 1

when the door :isClosed, .ente sZintO asmall groove 22 in'lockwing When ;a normalicoin is inserted, this :latter runs smoothly along the piece 17, the upper edge of which is rather sharp. If the coin is too thin, it will jam between piece 17 and the back of the coin chute, and on the handle of the door being pulled the point of screw 21 is moved out of the groove 22 of, the lockwing 3 and the coin is released, and falls down through a suitable chute into a bowl 23. Door 1 can, when no coin is found opposite screw 10, n0t turn more than the small part represented by the distance from the point of stopper 7 to the notch 4. This small turn is however sufiicientto bring the point of screw 21 out of the groove 22 in.

the lockwing 3, so that arm 20 turns sufliciently for piece 17 to release the jammed worn coin.

Coins of a too small diameterwill pass screw 10 without being held. Itwill easily be seen that this arrangement by very few mechanical means acts reliably, and does not react with worn or too small coins.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is: v

1. In a salesdevicaa coin chute, a door,

having on its inner face an inwardly projecting member, and a movable locking member projecting into thefcoin chute .to retain a coin therein, and cooperating with the member of the-door to lock the same when there is no coin inthe said chute and held in inoperative locking position by a coin in the chute to permit the door to be opened.

having an inwardly projecting member on its inner face and a pivoted and spring pressed locking member projecting into the chute to retain a coin therein, and cooperating with themember of the door to lock the same when there is no coin in the chute I if 2. In a sales'device, a coin chute, a door i and held in inoperative locking position by a coin in said chute to permit the door to be opened, and means for operating the looking member when the door is opened to release the coin.

8. In a sales device, a coin chute, adoor having a quadrant shaped and notched member on its inner face and a pivoted and spring pressed locking member carrying a screw projecting into the coin chute to retain a coin therein and adapted to engage the notch of the door member to lock the door when there is no coin in the chute, said locking member being held out of engagement with the said notch by a coin in the chute, and means on the door member for operating the locking member to release the coin when the door is opened.

a. In a sales device, a door having an inwardlyprojecting member on its inner face, a coin chute havingan opening in its bot- Gopies of this patent may be obtained for tom, a resiliently mounted member in the opening of the chute, and means ooacting with the member of the door for permitting the member in the opening of the coin chute to release the coin when the door is opened.

5. In a sales device, a door having an in-- wardly projecting member on its inner face, said member being provided with a recess,

coin chute having an opening in its bottom, a wedge shaped member resiliently supported on the chute and located in the opening of the said chute and an arm connected with the resilient supporting means of the said wedge-shaped member and provided with a screw normally engaging the recess of the door member.

In testimony whereof I aliix my signature.
